30-Minutes Estimation

Every estimate you've ever given a client was wrong.

Not because you're bad at estimating — because you were asked the wrong question. "How long will this take?" has no single answer. And the moment you give one, you've already set yourself up to fail.

If you run a small team, freelance, or manage projects because someone has to — you know exactly what happens next. The project runs over. The margin disappears. The client calls asking why it's late. And you promise yourself you'll estimate better next time.

You won't. Not unless you change how you think about estimates.

The 30-Minute Estimate is not a textbook. It's a short, blunt, practical guide that shows you why single-number estimates are a trap — and gives you a better way to quote projects, talk to clients, and protect your margins. No jargon. No statistics. No 400-page methodology. Just the thinking and the tools you need, in a book you can read in a single sitting.

Inside, you'll discover why your "most likely" estimate is almost certainly too low, how a reasonable range collapses into a promise you can't keep, a 20-minute spreadsheet exercise that reveals what your gut can't, word-for-word scripts for presenting ranges to clients, how to run a 30-minute team estimation session, what to do when the estimate blows up, and how to build an estimation memory that makes every future quote better than the last.

Written for small business owners, freelancers, agency leads, startup founders, consultants — anyone who quotes projects to clients and is tired of getting it wrong.

Book 2 in The 30-Minute Series. From the author of The 30-Minute Risk Plan. Same format: short, opinionated, and immediately actionable. Each book stands alone.
